I would like to see some source code or maybe a link to some that gives at least a stub for writing ruby gems in the C languages (C++?? is that possible too?)

Also, some of you may know that Facebook compiles some of their code natively as php extensions for better performance. Is anyone doing this in Rails? If so, what has been your experience with it? Have you found it to be useful?

Thanks.

Edit: I guess I'll answer my own question with some stuff I learned today but I'm going to leave the question open for another answer because I'd like to see what others have to say on this topic
